You don’t necessarily need a 50, your 3/6/4 is what’s hurting you. You aren’t at the minimum yet. I would aim for a 7/7/7 your OAR is just to get to the board it’s not often the deal breaker. Your PFAR the middle school is what’s looked at the most from speculation of reading through the thread. Nobody knows exactly what factors into your PFAR but speculation has it that, ANIT, and your PBM (stick, UAV portion) have a correlation to your PFAR!
Kyles Drive has great ANIT study practice, use the Jantzen for stick practice and the ASTB app with the ENS tab for UAV practice! Good luck!
